Why does the car not start and there is no response when turning the key?
3 Answers
Reasons and solutions for the car not starting and no response when turning the key are as follows: Insufficient fuel: First, check if the fuel level is insufficient. When the car lacks its power source, "gasoline," it naturally won't start. If the issue is caused by running out of fuel, the solution is straightforward. Depending on your situation, you can seek help from nearby car owners, borrow fuel, or arrange for towing to a gas station as emergency measures. Incorrect gear position: An incorrect gear position can also prevent the car from starting. Generally, the correct gear positions for starting an automatic transmission car are P (Park) or N (Neutral). If the driver accidentally leaves the gear in R (Reverse) or another position, not only will the car fail to start, but it may also pose a safety hazard. Electrical circuit malfunction: If the issue is related to the electrical circuit, the car's failure to start can be sudden. Common faults that cause the car not to start or respond include blown fuses, open circuits in the high-voltage coil, open circuits in the low-voltage circuit, detached central ignition wire, leaking distributor rotor, or damaged spark plugs. Further inspection and repair are needed.
I've encountered this situation before—turning the key and hearing absolutely no sound, which is most likely a dead battery. Try checking if the dome light or dashboard lights up; if they don't, just jump-start it. It could also be a loose starter connection—that part is located at the back of the engine, so you'll need someone to check if the screws are loose. Another easily overlooked issue is a blown starter fuse—just find the 15A fuse labeled 'ST' in the fuse box under the steering wheel and replace it. Automatic transmission cars can also have this problem if they're in the wrong gear—make sure you're pressing the brake and in P mode before starting. For older cars, check the ignition switch contacts—if the copper plates inside are worn out, they can cause poor contact.
If turning the key yields no response at all, don't panic immediately. Just yesterday, my neighbor's car had the same issue—upon inspection, I found the battery terminals were corroded with green crystalline buildup on the posts. Pouring hot water over them and scrubbing clean with sandpaper did the trick. A faulty gear selector switch can also trick the computer into thinking the car isn't in Park—try shifting the automatic transmission lever back and forth a few times. While you're at it, check if the brake lights illuminate when pressed; if not, a failed brake light switch might be causing a chain reaction. For vehicles with aftermarket wiring modifications, pay special attention to relays, as non-OEM parts often prevent the control module from receiving the start signal. As a last resort, gently tap the starter motor housing with a wrench—sometimes a stuck carbon brush can be freed with a couple of light knocks.
